HEAT-PRODUCING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 344,615, dated June 29, 1886.

Application filed Lugust 25, 1885. Serial No. 175,326. (No model.)

To all whom it may concern.-

Be it known that we, GEORGE E. BENNING- HOFF and COLLIN F. J EWELL, citizens of the United States, residing at Kendall Creek, in

the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Heat-Producing Apparatus; and we do hereby declare the following to be a full, clear, and exact description of the in- IO vention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

The object of this improvement is an eco nomical and intense heat-producing fuel, pro- 1 duced by mixing air and gas under pressure, and suitable mechanical means for practically applying the same to blacksmithing, various metalworking, and to heating purposes in general,by introducing the sameinto the combuszo tionchamber of a forge or furnace in a thoroughly-blended state. These results are attained by the process hereinafter described, and the mechanism illustrated in the drawings herewith filed as part hereof, in which the same letters of reference denote the same parts in the different views.

Figure 1 is a plan. Fig. 2 is a side elevation. Fig. 3 is a vertical section taken centrally. Fig. 4 is a representation of the gasoxygenizers on enlarged scale. Fig. 5 is alongitudinal section of same.

A represents brick or stone masonry forming aforge, the inner part of which may be formed of, fire-brick, and the whole inclosed 5 in a metal cylinder and cap conforming thereto.

A is a spherical combustionchamber pro vided with an escape, A and opening A of any suitable size for introducing into the combustionchambcr bars to be heated. The com- 0 bust-ion-charnber may be oval, cylindrical in form, or otherwise, as may be deemed advisable, and the same may be changed to suit the purposes for which the heat is to be applied.

B is a blast-pipe connected, through a union- 5 piece, I), and blast-conduit B B, with gasoxygenizersC G, the interior construction of which is fully illustrated in Fig. 4.

1) 1) are gas-supply pipes connected with oxygenizers O G, and G G are conduit-pipes forintroducing oxygenized gas into the com- 53 bustion-chamber A.

E is ablast-pipe connected through a unionpiece, E, with blast conduit E, connected through union-pieces E with gas-oxygenizers F F, and through curved continuation of pipe 55 E, as shown at ff, with gas-oxygenizers F F, which are provided with gas-supply pipes G G, having, stopcocks G G, as fully shown in Fig. 2.

F F are conduit-pipes connected with and having a direction from the gas-oxygenizers F F toward the center of the combustionchamber A, for the purpose of producing a blast concentric with the combustion-chamber A, and thereby attain a thorough blending of the elements of combustion in all the parts of the chamber.

E* is an air-blast condoitpipe connected through the union-piece E with the blast-pipe E and thence directed through recessa of the forge A and a recess in the vertical center of the latter to the combustion-chamber A, as fully shown in Fig. 3.

Referring to Figs. 4, 5, O G represent the gas oxygenizers on an enlarged scale. 0 is the 7 5 air-and-gas-mixing chamber. To their rectangular extensions 0 the gas'supply pipes D and G are suitably connected. The parts d d are provided with screw-threads for connection therewith of blastpipes B and E and oxygenized-gas conduits 0 F The blast-pipes B and E may be connected to and supplied with air through a single blast-conduit connecting with a fan or other suitable mechanism for producing asimilar result. The operation is as follows: Glas will flow into the chambers c of the oxygenizers O and F F through the pipesD G, and will beblended in the chambers c with the air-blast entering 0 the latter through the pipes 13 E, and will be forced thence through the conduit-pipes G and F in a thoroughly-mixed state into the combustion-chamber A, where the different currents of air and oxygenized gas will blend with each other, and thus be put in condition for thorough combustion, from which a very intense heat will beproduced more economically than is otherwise practicable. The vertical blast through the pipe E will assist the blending of the. different currents introduced into the combustion-chamber and the-action of the heat in a vertical direction.

The pipe E may be provided with a stopcock for stopping entirely or partially reducing the force of the blast through the same, as occasion may require.

The stop-cocks G Gof thesupply-pipe connecting with the oxygenizers FF may be used for partially or entirely cutting off the flow of gas into the oxygenizers, as occasion may require, and the pipes E E used as air-conduits only.

I The form of oxygenizer herein described is preferable for producing a suitable mixture of gas and air; but the same may be more or less modified without altering the spirit ofour invention or departing substantially from the construction shown. We therefore do not confine ourselves strictly to the form described, but may use any suitable construction for the same that is adapted to produce the result specified.

Having explained the features of our improvement, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, in afurnacc, ofthe combustion-chamber, the air and gas supply pipes, the oxygenizers or mixing-chambers, and the conduits extending through the furnace-wall,

the area in cross-section of the mixing-chambei's being greater than the sum of the similar areas of the pipes, and that of the conduits equal to said sum, substantially as and for the purpose set forth.

2. The combination, in a' furnace, ofa combustion-chamber, the air and gas supply pipes, the oxygenizers or mixing-chambers, and the conduits extending through the furnace-wall for introducing into the combustion-chamber sub-currents of air or gas, or air and gas, and distributing the combustion to-all parts of or 10- cati mg the heat of the same in any desired part of the combustion-chamber, substantially as specified, for the purpose set forth.

3. The combination, in a furnace, ol'a combustion-chamber,the air and gas supply pipes, the oxygenizers or mixing-chambers, the conduits extending through the furnace-walls in positions opposite to each other, and the conduit extending into the body of the furnace and vertically through the center of the same to the combustion-chamber, as and for the purpose set 'forth.

In testimony whereof we affix oursignatures in presence of two witnesses.
